SAWSETTING TOOL. o

Specification of Letters Patent.

Patented Dec. f3, i909.

Application filed. November 3, 1908. Serial No. 460,896.

' Pittseld, county of Berkshire, and State of i Tools, of which the following is a specificavation with parts in section: Fig.

ILO

Massachusetts, have invented certain new and useful lmprovements in Saw Setting tion, reference being had therein to the ac companying drawing.

This invention relates to a. combination tool of the pincer type, and particularly to a structure adapted to receive saw setting jaws or jaws for other uses.

An object of the invention is to provide a novel and improved form of saw setting jaws one of which comprises an anvil member having a device adjustable relative to the thickness of thesaw and an opposing setting member providedwith a beveled point and adjustable means for determining the depth or length of the tooth to be set. Other and further` objects and advantages of the invention will be hereinafter fully set forth and the novelvfeatures ,thereof defined by the appended claims.

In the vdrawingz-Figure 1 is a side ele- 2 is a top plan: Fig. 3 is a detail perspective of the anvil jaw: Fig. 4 is asimilar view of the cooperating setting jaw: Fig. 5 is an elevation vwith parts in section of the setting jaw: Fig.

6 is an elevation showing the application of a modified form of jaw to the handle members.

Like numerals refer to like parts in the several views of the drawing.

The numerals 10 and 11 designate the handle members of the pincers by which they are operated, these members being pivoted together at l2 and each provided with a socket 13 to receive the jaws to be used therewith. Extending from one of these sockets is the fulcrum 1a having the curved outer face 15 adapted to be rocked upon the base, as indicated in Fig. 6, 'when the jaws are applied for pulling purposes.' Each of the jaws used herein is provided with a shank 16 havin an aperture laterally therethrough and isposed in alinement with corresponding apertures in the side I'walls of the recess 13. Through these apertures the holding pin 17 is passed, this pin being of any desired configuration, preferably, tapering, as shown in Fig. 2. The handle members are normally separated by means of the spring 18 secured to one member at 19 and bearing at its end 2O upon the opposite member, while the extent of movement of the handles toward eachother and the consequent travel of the jaws carried thereby is limited by a screw 'member 21 threaded in the socketI 22 carried'by one of the handles and adapted at its free end 28 to engage the opposite handle. This screw is provided with the operating head 2l and the lock nut 25.

The handle members may be provi-ded with jaws of different characters, but a novel and improved form of saw setting jaw is shown in Figs. 1 to 5, and comprises the base or anvil jaw 2G having a depressed portion 27 atits rear and the goose neck wall 28 at one side thereof provided with the threaded laterally disposed lug 29. ln this lug the screw 30 is mounted and is adjustable toward and from the upper face of the anvil 26 relative to the thickness of the saw blade so that it may be held against lateral movement during the setting action. This screw is adapted to be locked in position by the nut 31, as shown, and the anvil is provided with the shank 16 having an aperture to receive the pin. `17 as before described. Cooperating with this anvil jaw isthe setting jaw 32 having its front or point tapered to substantially lbshaped, as shown at 33 so as to engage a side of the saw tooth and force it laterally to the saw body during the setting action. The Linder side of this setting jaw is fiat and provided with a gage plate 34 by which the depth or length of the saw tooth to be bent is determined, this gage being carried by a slotted plate 85 which is adjustably mounted on the under tace of the jaw by means of the screw 36, as shown in Fig. 5. Other forms of jaws may be used, for instance, as shown in Fig. 6, where nail drawing jaws 37 may be applied to the handle members and cooperate with the fulcrum extension 14: insecuring the leverage for withdrawing nails or other objects grasped by these jaws.

In the operation oi the saw setting jaws it will be seen that the anvil member is adjustable relative to the thickness of the saw, while the depth or length of the tooth to be set may be gaged by the plate carried by the setting member so that the tapered. portion of this plate extending beyond the gage contacts with the tooth and edects the setting toward each other, and the extent of such,

movement and the consequent lateral deflection of the tooth is governedV by the screw member carried by one of the jaws and engaging the other jaw. It will be obvious that thes saw setting members may be re` moved w en their use is not desired, 4and other members, such as shown in Fig. 6 substituted, thus rendering the tool capable of numerous uses by. simpl substituting jaws of different characters. 'Ihe invention therefore presents a'sim le, economically manufacturedv and very e cient tool in the arts.

Having described my invention and set forth its merits, whatI claim and desire to secure by Letters Patent iszl 1. In a tool of the class described, pivoted ,handle members, an anvil jaw carried by one of said members and having a flat supporting face and a saw setting recess, any auxiliary setting jaw having an inclined setting point disposed to travel above the recess of said anvil, and a gage plate mounted upon the under face of said setting jaw and having a depending portion extending laterally o-the setting point and adapted to engage the tooth being set.

2. In a tool of the class described, pivoted handle members, an anvil jaw carried by one of said members and having a flat supporting surface and a saw setting recess, an

Ihandle members, a jaw mounted 1n one of said members and having a fixed flat anvil face and a recessed portion at its rear, an upward extension at one side of said face provided with a laterally disposed threaded socket, an adjusting screw mounted in said socket for movement toward and from the anvil face of the djaw, and a cooperating set ting jaw carrie by the opposite handle member and having a gage plate mounted ,thereon with a depending portion extending laterally of the setting point and adjustable relatively to the point ofv said setting jaw.

In testimony whereof I aiiix my signature in presence of two witnesses.
